Israel (יִשְׂרָאֵל; إِسْرَائِيل), formally known as the State of Israel (מְדִינַת יִשְׂרָאֵל ''''), is a country in Western Asia, located on the southeastern shore of the Mediterranean Sea and the northern shore of the Red Sea. It has land borders with Lebanon to the north, Syria to the northeast, Jordan on the east, the Palestinian territories of the West Bank and Gaza Strip to the east and west, respectively, and Egypt to the southwest. The country contains geographically diverse features within its relatively small area. Israel's economic and technological center is Tel Aviv, while its seat of government and proclaimed capital is Jerusalem, although the state's sovereignty over Jerusalem has only partial recognition. Israel has evidence of the earliest migration of hominids out of Africa. Canaanite tribes are archaeologically attested since the Middle Bronze Age, The successful Maccabean Revolt led to an independent Hasmonean kingdom by 110 BCE, which in 63 BCE however became a client state of the Roman Republic that subsequently installed the Herodian dynasty in 37 BCE, and in 6 CE created the Roman province of Judea. Judea lasted as a Roman province until the failed Jewish revolts resulted in widespread destruction, and the renaming of the region from Iudaea to Syria Palaestina. Jewish presence in the region has persisted to a certain extent over the centuries. In the 7th century CE, the Levant was taken from the Byzantine Empire by the Arabs and remained in Muslim control until the First Crusade of 1099, followed by the Ayyubid conquest of 1187. The Mamluk Sultanate of Egypt extended its control over the Levant in the 13th century until its defeat by the Ottoman Empire in 1517. During the 19th century, national awakening among Jews led to the establishment of the Zionist movement in the diaspora followed by waves of immigration to Ottoman Syria and later Mandatory Palestine. In 1947, the United Nations (UN) adopted a Partition Plan for Palestine recommending the creation of independent Arab and Jewish states and an internationalized Jerusalem. Israel has since fought several wars with Arab countries, and since the Six-Day War in June 1967 held occupied territories including the West Bank, Golan Heights and the Gaza Strip (still considered occupied after the 2005 disengagement, although some legal experts dispute this claim). It extended its laws to the Golan Heights and East Jerusalem, but not the West Bank. Israel's occupation of the Palestinian territories is the world's longest military occupation in modern times. Efforts to resolve the Israeli–Palestinian conflict have not resulted in a final peace agreement, while Israel has signed peace treaties with both Egypt and Jordan. In its Basic Laws, Israel defines itself as a Jewish and democratic state and the nation state of the Jewish people. The country has a liberal democracy (one of only two in the Middle East and North Africa region, the other being Tunisia), with a parliamentary system, proportional representation, and universal suffrage. The prime minister is head of government and the Knesset is the legislature. With a population of around 9 million as of 2019, Israel is a developed country and an OECD member. It has the world's 31st-largest economy by nominal GDP, and is the most developed country currently in conflict. It has the highest standard of living in the Middle East, percentage of citizens holding a tertiary education degree, research and development spending by GDP percentage, women's safety, life expectancy, innovativeness, and happiness.

Georgia is a country in the Caucasus region of Eurasia. Located at the crossroads of Western Asia and Eastern Europe, it is bounded to the west by the Black Sea, to the north by Russia, to the south by Turkey and Armenia, and to the southeast by Azerbaijan. The capital and largest city is Tbilisi. Georgia covers a territory of and its approximate population is about 3.718 million. Georgia is a unitary parliamentary republic, with the government elected through a representative democracy. During the classical era, several independent kingdoms became established in what is now Georgia, such as Colchis and Iberia. The Georgians officially adopted Christianity in the early 4th century. The Georgian Orthodox Church had enormous importance for the spiritual and political unification of early Georgian states. The unified Kingdom of Georgia reached its Golden Age during the reign of King David the Builder and Queen Tamar the Great in the 12th and early 13th centuries. Thereafter, the kingdom declined and eventually disintegrated under the hegemony of various regional powers, including the Mongols, the Ottoman Empire and successive dynasties of Iran. In the late 18th century, the eastern Georgian Kingdom of Kartli-Kakheti forged an alliance with the Russian Empire, which directly annexed the kingdom in 1801 and conquered the western Kingdom of Imereti in 1810. Russian rule over Georgia was eventually acknowledged in various peace treaties with Iran and the Ottomans and the remaining Georgian territories were absorbed by the Russian Empire in a piecemeal fashion through the course of the 19th century. During the Civil War following the Russian Revolution in 1917, Georgia briefly became part of the Transcaucasian Federation and then emerged as an independent republic before the Russian army invasion in 1921, which established a government of workers' and peasants' soviets. Soviet Georgia would be incorporated into a new Transcaucasian Federation that, in 1922, would be a founding republic of the Soviet Union. In 1936, the Transcaucasian Federation was dissolved and Georgia emerged as a Union Republic. During World War II, almost 700,000 Georgians fought in the Red Army against the Germans. After Soviet leader Joseph Stalin, a native Georgian, died in 1953, a wave of protest spread against Nikita Khrushchev and his de-Stalinization reforms, leading to the death of nearly one hundred students in 1956. By the 1980s, an independence movement was established and grew, leading to Georgia's secession from the Soviet Union in April 1991. For most of the following decade, post-Soviet Georgia suffered from civil conflicts, secessionist wars in Abkhazia and South Ossetia, and economic crisis. Following the bloodless Rose Revolution in 2003, Georgia strongly pursued a pro-Western foreign policy; aimed at NATO and European integration, it introduced a series of democratic and economic reforms. This brought about mixed results, but strengthened state institutions. The country's Western orientation soon led to the worsening of relations with Russia, culminating in the brief Russo-Georgian War in August 2008 and Georgia's current territorial dispute with Russia. Georgia is a developing country and ranks 70th on the Human Development Index. The country is a member of the United Nations, the Council of Europe, and the GUAM Organization for Democracy and Economic Development. It contains two de facto independent regions, Abkhazia and South Ossetia, which gained very limited international recognition after the 2008 Russo-Georgian War. Most of the world's countries consider the regions to be Georgian territory under Russian occupation.

Bulgaria (България), officially the Republic of Bulgaria (Република България, ), is a country in Southeastern Europe. It is bordered by Romania to the north, Serbia and North Macedonia to the west, Greece and Turkey to the south, and the Black Sea to the east. The capital and largest city is Sofia; other major cities are Plovdiv, Varna and Burgas. With a territory of Bulgaria is Europe's sixteenth-largest country. One of the earliest societies in the lands of modern-day Bulgaria was the Neolithic Karanovo culture, which dates back to 6,500 BC. In the 6th to 3rd century BC the region was a battleground for ancient Thracians, Persians, Celts and Macedonians; stability came when the Roman Empire conquered the region in AD 45. The Eastern Roman Empire lost some of these territories to Slavic and then Turkic Bulgar invaders in the late 7th century. The Bulgars founded the First Bulgarian Empire in AD 681, which dominated most of the Balkans and significantly influenced Slavic cultures by developing the Cyrillic script. This state lasted until the early 11th century, when Byzantine emperor Basil II conquered and dismantled it. A successful Bulgarian revolt in 1185 established a Second Bulgarian Empire, which reached its apex under Ivan Asen II (1218–1241). After numerous exhausting wars and feudal strife, the empire disintegrated in 1396 and fell under Ottoman rule for nearly five centuries. The Russo-Turkish War of 1877–78 resulted in the formation of the third and current Bulgarian state. Many ethnic Bulgarians were left outside the new nation's borders, which stoked irredentist sentiments that led to several conflicts with its neighbours and alliances with Germany in both world wars. In 1946 Bulgaria came under the Soviet-led Eastern Bloc and became a one-party socialist state The ruling Communist Party gave up its monopoly on power after the revolutions of 1989 and allowed multiparty elections. Bulgaria then transitioned into a democracy and a market-based economy. Since adopting a democratic constitution in 1991, Bulgaria has been a unitary parliamentary republic composed of 27 provinces, with a high degree of political, administrative, and economic centralisation. Bulgaria is a member of the European Union, NATO, and the Council of Europe; it is a founding state of the Organization for Security and Co-operation in Europe (OSCE) and has taken a seat on the UN Security Council three times. Its market economy is part of the European Single Market and mostly relies on services, followed by industry—especially machine building and mining—and agriculture. Bulgaria is a developing country and ranks 52nd in the Human Development Index, the lowest development rank in the European Union alongside Romania. Widespread corruption is a major socioeconomic issue; Bulgaria ranked as the most corrupt country in the European Union in 2018. The country also faces a demographic crisis, with its population shrinking annually since the late 1980s; it currently numbers roughly seven million, down from a peak of nearly nine million in 1988.

Greece (Ελλάδα, ), officially the Hellenic Republic, known also as Hellas, is a country located in Southeast Europe. Its population is approximately 10.7 million as of 2018; Athens, the nation's capital, is its largest city, followed by Thessaloniki. Situated on the southern tip of the Balkan Peninsula, Greece is located at the crossroads of Europe, Asia, and Africa. It shares land borders with Albania to the northwest, North Macedonia and Bulgaria to the north, and Turkey to the northeast. The Aegean Sea lies to the east of the mainland, the Ionian Sea to the west, the Cretan Sea and the Mediterranean Sea to the south. Greece has the longest coastline on the Mediterranean Basin and the 11th longest coastline in the world at in length, featuring many islands, of which 227 are inhabited. Eighty percent of Greece is mountainous, with Mount Olympus being the highest peak at . The country consists of nine traditional geographic regions: Macedonia, Central Greece, the Peloponnese, Thessaly, Epirus, the Aegean Islands (including the Dodecanese and Cyclades), Thrace, Crete, and the Ionian Islands. Greece is considered the cradle of Western civilisation, being the birthplace of democracy, Western philosophy, Western literature, historiography, political science, major scientific and mathematical principles, Western drama and the Olympic Games. From the eighth century B.C., the Greeks were organised into various independent city-states, known as poleis (singular polis), which spanned the entire Mediterranean region and the Black Sea. Philip of Macedon united most of the Greek mainland in the fourth century BC, with his son Alexander the Great rapidly conquering much of the ancient world, from the eastern Mediterranean to India. Greece was annexed by Rome in the second century B.C., becoming an integral part of the Roman Empire and its successor, the Byzantine Empire, which adopted the Greek language and culture. The Greek Orthodox Church, which emerged in the first century A.D., helped shape modern Greek identity and transmitted Greek traditions to the wider Orthodox World. After falling under Ottoman dominion in the mid-15th century, Greece emerged as a modern nation state in 1830 following a war of independence. The country's rich historical legacy is reflected in part by its 18 UNESCO World Heritage Sites. Greece is a unitary parliamentary republic and developed country with an advanced high-income economy, a high quality of life, and a very high standard of living. Its economy is the largest in the Balkans, where it is an important regional investor. A founding member of the United Nations, Greece was the tenth member to join the European Communities (precursor to the European Union) and has been part of the Eurozone since 2001. It is also a member of numerous other international institutions, including the Council of Europe, the North Atlantic Treaty Organization (NATO), the Organisation for Economic Co-operation and Development (OECD), the World Trade Organization (WTO), the Organization for Security and Co-operation in Europe (OSCE), and the Organisation internationale de la Francophonie (OIF). Greece's unique cultural heritage, large tourism industry, prominent shipping sector and geostrategic importance classify it as a middle power.

Poland (Polska ), officially the Republic of Poland (Rzeczpospolita Polska ), is a country located in Central Europe. It is divided into 16 administrative subdivisions, covering an area of and has a largely temperate seasonal climate. With the passing of prominence and prosperity, the country was partitioned by neighbouring states at the end of the 18th century, and regained independence in 1918 with the Treaty of Versailles. After a series of territorial conflicts, the new multi-ethnic Poland restored its position as a key player in European politics. In September 1939, World War II began with the invasion of Poland by Nazi Germany, followed by the Soviet Union invading Poland in accordance with the Molotov–Ribbentrop Pact. Approximately six million Polish citizens, including three million of the country's Jews, perished during the course of the war. As member of the Eastern Bloc, the Polish People's Republic proclaimed forthwith was a chief signatory of the Warsaw Treaty amidst global Cold War tensions. In the wake of the 1989 events, notably through the emergence and contributions of the Solidarity movement, the communist government was dissolved and Poland reestablished itself as a presidential democratic republic.

Sweden (Sverige ), officially the Kingdom of Sweden (links=no ), is a Nordic country in Northern Europe. It borders Norway to the west and north, Finland to the east, and is connected to Denmark in the southwest by a bridge-tunnel across the Öresund Strait. At Sweden is the largest country in Northern Europe, the third-largest country in the European Union and the fifth largest country in Europe by area. The capital city is Stockholm. Sweden has a total population of 10.3 million Persons who have foreign backgrounds are defined as persons who are foreign born, or born in Sweden with foreign born parents. It has a low population density of and the highest urban concentration is in the central and southern half of the country. Sweden is part of the geographical area of Fennoscandia. The climate is in general mild for its northerly latitude due to significant maritime influence. In spite of the high latitude, Sweden often has warm continental summers, being located in between the North Atlantic, the Baltic Sea and the vast Eurasian Russian landmass. The general climate and environment varies significantly from the south and north due to the vast latitudal difference and much of Sweden has reliably cold and snowy winters. Southern Sweden is predominantly agricultural, while the north is heavily forested and includes a portion of the Scandinavian Mountains. Germanic peoples have inhabited Sweden since prehistoric times, emerging into history as the Geats (Swedish Götar) and Swedes (Svear) and constituting the sea peoples known as the Norsemen. An independent Swedish state emerged during the early 12th century. After the Black Death in the middle of the 14th century killed about a third of the Scandinavian population, the Hanseatic League threatened Scandinavia's culture, finances and languages. This led to the forming of the Scandinavian Kalmar Union in 1397, which Sweden left in 1523. When Sweden became involved in the Thirty Years War on the Reformist side, an expansion of its territories began and eventually the Swedish Empire was formed. This became one of the great powers of Europe until the early 18th century. Swedish territories outside the Scandinavian Peninsula were gradually lost during the 18th and 19th centuries, ending with the annexation of present-day Finland by Russia in 1809. The last war in which Sweden was directly involved was in 1814, when Norway was militarily forced into a personal union, which peacefully dissolved in 1905. Since then, Sweden has been at peace, maintaining an official policy of neutrality in foreign affairs. In 2014, Sweden celebrated 200 years of peace, breaking even Switzerland's record for peace. Sweden was formally neutral through both world wars and the Cold War, albeit Sweden has since 2009 openly moved towards cooperation with NATO. Sweden is a constitutional monarchy and a parliamentary democracy, with Legislative power vested in the 349-member unicameral Riksdag.

The Czech Republic (Česká republika ), also known by its short-form name, Czechia (Česko ), is a landlocked country in Central Europe bordered by Austria to the south, Germany to the west, Poland to the northeast and Slovakia to the southeast. The Czech Republic has hilly landscape that covers an area of with a mostly temperate continental climate and oceanic climate. It is a unitary parliamentary republic, with million inhabitants. Its capital and largest city is Prague, with 1.3 million residents; other major cities are Brno, Ostrava, Olomouc and Pilsen. The Czech state was formed in the late 9th century as the Duchy of Bohemia under the Great Moravian Empire. In 1002, the duchy was formally recognized as an Imperial State of the Holy Roman Empire, and became the Kingdom of Bohemia in 1198, reaching its greatest territorial extent in the 14th century. Prague was the imperial seat in periods between the 14th and 17th century. The Bohemian Reformation of the 15th century led to the Hussite Wars, which resulted in a period of confessional pluralism and relative religious tolerance. Following the Battle of Mohács in 1526, the whole Crown of Bohemia was gradually integrated into the Habsburg Monarchy. The Protestant Bohemian Revolt (1618–20) against the Catholic Habsburgs led to the Thirty Years' War. After the Battle of the White Mountain, the Habsburgs consolidated their rule, reimposed Catholicism, and adopted a policy of gradual Germanization. With the dissolution of the Holy Roman Empire in 1806, the Bohemian Crown lands became part of the Austrian Empire, and the Czech (Bohemian) language and literature experienced a cultural revival. In the 19th century, the Czech lands became heavily industrialized and were subsequently the core of the First Czechoslovak Republic, which was formed in 1918 following the collapse of the Austro-Hungarian Empire after World War I. Czechoslovakia was the only democracy in Central Europe during the interwar period. However, beginning in 1938, Nazi Germany systematically annexed the Czech Lands, while Slovakia became a German puppet state. The country was restored in 1945. Most members of the German-speaking minority were expelled following the war. The Communist Party of Czechoslovakia won a plurality in the 1946 elections and after the 1948 coup d'état established a one-party communist state under Soviet influence. Increasing dissatisfaction with the regime culminated in 1968 to the reform movement known as the Prague Spring, which ended in a Soviet-led invasion. Czechoslovakia remained occupied until the 1989 Velvet Revolution, which peacefully ended communist rule and reestablished democracy with a market economy. On 1 January 1993, Czechoslovakia peacefully dissolved, with its constituent states becoming the independent states of the Czech Republic and Slovakia. The Czech Republic joined NATO in 1999 and the European Union in 2004. It is also a member of the OECD, the United Nations, the OSCE, and the Council of Europe. The Czech Republic is a developed country with an advanced, high income social market economy. It is a welfare state with a European social model, universal health care, and tuition-free university education. It ranks 13th in the UN inequality-adjusted human development and 14th in the World Bank Human Capital Index ahead of countries such as the United States, the United Kingdom and France. It ranks as the eleventh safest and most peaceful country and performs well in democratic governance.

In 988 it adopted Orthodox Christianity from the Byzantine Empire, beginning the synthesis of Byzantine and Slavic cultures that defined Russian culture for the next millennium. Rus' ultimately disintegrated into a number of smaller states, until it was finally reunified by the Grand Duchy of Moscow in the 15th century. By the 18th century, the nation had greatly expanded through conquest, annexation, and exploration to become the Russian Empire, which was the third largest empire in history, stretching from Norway on the west to Alaska on the east. Following the Russian Revolution, the Russian Soviet Federative Socialist Republic (Russian SFSR) became the largest and leading constituent of the Union of Soviet Socialist Republics (USSR/Soviet Union), the world's first constitutionally socialist state. The Soviet Union played a decisive role in the Allied victory in World War II, and emerged as a recognised superpower and rival to the United States during the Cold War. The Soviet era saw some of the most significant technological achievements of the 20th century, including the world's first human-made satellite and the launching of the first humans in space. Following the dissolution of the Soviet Union in 1991, the Russian SFSR reconstituted itself as the Russian Federation and is recognised as the continuing legal personality and a successor of the USSR.
